Florida police have slammed the brakes on a prostitution ring which got its clients off on the go.

A massive limo bus police are calling a "brothel-on-wheels" was allegedly the site of all kinds of sexual encounters while trolling the streets of Miami's South Beach.

"It was very brazen," said a police spokesman. "They were offering everything from lap dances to sex."

Cops caught onto the scheme when some of the women on board jumped out of the bus and offered them an all-you-can-drink deal for $40. After the officers got on board, the ladies stripped down for some lap dances and offered oral sex in a curtained-off VIP room.

The six people running the bus face an array of charges that include, aside from prostitution, "violating the public dance hall ordinance (the women were technically 'dancing') to possession of a controlled substance (the driver had six tablets of Viagra on him at the time of his arrest)."
